Interchange fees are the charges a merchant’s bank pays to the customer’s card-issuing bank every time a card is used, and they usually run from about 1.5% to over 3% of each sale depending on the card and how the transaction is processed. They exist to compensate the issuing bank for fronting the money, absorbing fraud risk, and funding the interest-free grace period on credit cards. For most businesses that accept cards, interchange is the single largest line in the cost of accepting payments.
The fee is set by the card networks, moves from the acquiring bank to the issuing bank, and reaches the merchant bundled inside whatever the payment processor charges. You never pay the issuing bank directly, but you fund the whole chain.
How the Fee Is Calculated
Every interchange rate has two parts: a percentage of the sale and a flat per-transaction charge. A common consumer credit rate on Visa might be 1.80% plus $0.10. The percentage scales with the ticket size; the flat fee doesn’t move whether the customer spends $4 or $400.
On a $50 sale at 1.80% + $0.10, interchange is $1.00. On a $10 sale at the same rate, it’s $0.28. That flat fee takes a much bigger proportional bite out of small purchases, which is why coffee shops and convenience stores feel interchange differently than furniture stores. The acquiring bank deducts the fee before depositing the rest of the sale into the merchant’s account.
Who Gets Paid on a Card Transaction
Four parties sit inside every card sale, and each takes a piece:
- The merchant accepts the card and is the ultimate source of every processing fee.
- The acquiring bank manages the merchant’s account, connects the business to the card networks, and adds its own markup on top of interchange.
- The card network (Visa, Mastercard, and others) runs the rails that link the acquirer to the issuing bank and charges separate assessment fees for that service.
- The issuing bank gave the customer the card and receives the interchange fee itself.
The interchange payment moves from acquirer to issuer. The network facilitates the transfer but does not keep interchange revenue. What the merchant sees on a statement is a single deduction that bundles interchange, network assessments, and the acquirer’s margin.
Many merchants don’t sign up with an acquirer directly. They go through an Independent Sales Organization or payment service provider, a middleman that resells processing from one or more acquirers and adds its own margin. That extra layer is invisible to the cardholder but adds another mouth to feed. Knowing whether you’re working with a direct acquirer or a reseller matters when you sit down to negotiate.
What Determines the Rate on Any Given Sale
Interchange is not one rate. Visa and Mastercard each publish thousands of rate categories, and the rate that applies to a specific sale depends on several factors working together.
The Card the Customer Uses
Card type is the biggest driver. A basic consumer debit card from a large bank triggers the lowest regulated rate. A premium rewards credit card triggers some of the highest rates, because the issuing bank has to fund the points, miles, or cash-back the cardholder earns.
Mastercard’s published schedule shows standard consumer credit rates around 2.10% + $0.10 for a basic card-present transaction and 2.50% + $0.10 for World Elite cards. Non-qualified or fallback rates on consumer credit can reach 3.15% + $0.10 on both Visa and Mastercard.1Visa. Visa USA Interchange Reimbursement Fees Corporate and purchasing cards run higher still, with Mastercard’s commercial standard rates ranging from 3.10% to 3.30% + $0.10 depending on tier.2Mastercard.

How the Card Is Read
How the card enters the transaction affects fraud risk, and risk affects price. When a chip card is inserted or tapped, fraud exposure is lower and the interchange rate reflects that. When the card number is keyed in manually or submitted through online checkout, the sale is classified as card-not-present and carries a higher rate. The gap between card-present and card-not-present on the same card type can be 0.30% or more. That’s a big reason e-commerce merchants consistently pay more than brick-and-mortar shops selling the same goods.
Your Merchant Category Code
Every merchant gets a four-digit Merchant Category Code that classifies the business. Card networks use MCCs to group merchants into custom pricing programs; some industries get preferential rates and others pay a premium.3Mastercard. Quick Reference Booklet – Merchant Grocery stores, utilities, and charities tend to sit at the low end. Industries with high chargeback or fraud exposure, like online gambling and travel, sit at the high end. If your business was coded wrong during onboarding, you may be paying more than your industry warrants.
Small-Ticket Programs
If most of your sales are small, you may qualify for a small-ticket program. On Mastercard’s network, transactions of $5.00 or less can qualify for reduced rates with a much lower flat fee. A card-present consumer credit transaction at the Core level drops to 1.65% + $0.02 under the small-ticket program, compared with a standard rate carrying a $0.10 flat fee.4Mastercard.

Level 2 and Level 3 Data
Merchants that sell to businesses or government agencies can drop their interchange rates by submitting more data with each transaction. Level 2 processing adds fields like the tax amount and a purchase order number. Level 3 goes further, adding line-item detail: product codes, quantities, unit costs, shipping information. More data means less risk to the network, and the rate falls accordingly. Level 3 savings can roughly double what Level 2 delivers. A B2B or government-facing business that isn’t submitting this data is almost certainly overpaying.
Debit Cards Sit Under a Federal Cap
Debit interchange doesn’t work like credit. The Durbin Amendment, added to the Electronic Fund Transfer Act as part of the Dodd-Frank Act in 2010, directed the Federal Reserve to cap debit interchange at levels “reasonable and proportional” to the issuing bank’s actual cost of processing.
The Fed’s implementing rule, Regulation II, sets the cap at $0.21 plus 0.05% of the transaction.5eCFR. 12 CFR Part 235 – Debit Card Interchange Fees and Routing Banks that meet certain fraud-prevention standards can add a $0.01 adjustment, so the effective cap on a typical debit sale runs about $0.22 + 0.05%.6Office of the Law Revision Counsel. 15 USC 1693o-2 – Reasonable Fees and Rules for Payment Card Transactions On a $50 debit sale, that’s about $0.245 in interchange, versus $1.00 or more on a premium credit card at the same register.
Two important limits on the cap. First, it only applies to banks and credit unions with $10 billion or more in assets.7eCFR. 12 CFR 235.5 – Exemptions Smaller issuers are exempt and can charge higher debit interchange, so a debit card from a community bank or small credit union costs a merchant more to accept than one from a large national bank. The Fed publishes a yearly list of exempt and covered institutions.8Federal Reserve. Regulation II – Interchange Fee Standards: Small Issuer Exemption Second, the cap is debit only. Credit card interchange is not federally capped.
The Federal Reserve has proposed lowering the debit cap to $0.144 plus 0.04% with a $0.013 fraud adjustment. As of early 2026 the rule has not been finalized and faces legal challenges, so the current numbers still apply.
How Your Processor Prices You
You almost never pay raw interchange. You pay through a pricing model set by your acquirer or processor, which bundles interchange with its own markup. The model determines how visible your real costs are.
Interchange-Plus
Under interchange-plus, sometimes called cost-plus, the processor passes through the exact interchange rate the transaction qualified for and adds a fixed markup, such as 0.25% + $0.10. Every transaction on your statement shows the actual interchange category it hit, plus the processor’s margin. It’s the most transparent model. Statements are more complex because different card types produce different categories, but you can see what you’re paying and why.
Tiered Pricing
Tiered pricing groups all transactions into a handful of buckets, usually labeled qualified, mid-qualified, and non-qualified. The processor advertises a low qualified rate that covers the most common sale types and charges higher rates for cards or methods that don’t meet the qualified criteria. Rewards cards, keyed-in transactions, and unsettled batches often get bumped up.
The problem is that the processor decides which transactions land in which tier. A debit card carrying a low interchange rate can be billed to the merchant at the non-qualified rate, and the statement won’t show it. That mismatching is where tiered pricing quietly extracts margin, and it’s the reason experienced merchants tend to move off it.
Subscription or Membership Pricing
Some processors charge a flat monthly or annual fee instead of a percentage markup. The merchant pays interchange at cost plus a small per-transaction charge, often around $0.08 a swipe, with no percentage layered on by the processor. It favors high-volume merchants, because the monthly fee shrinks as a share of total processing costs as volume grows. For a low-volume shop, the fixed fee can make each sale more expensive than interchange-plus would.
What a Merchant Can Actually Do About It
You cannot negotiate interchange rates with the card networks. What you can do is control the factors that decide which rate category your transactions fall into, and which pricing model sits on top.
- Use chip and contactless. Card-present chip and tap transactions qualify for lower rates and avoid compliance fees tied to non-EMV terminals.
- Settle batches daily. Failing to close a batch within 24 hours can push transactions into higher mid-qualified or non-qualified tiers.
- Submit Level 2 and Level 3 data if you sell to businesses or government agencies. Adding tax amounts, purchase order numbers, and line-item detail can cut commercial card interchange substantially.
- Verify your MCC. An incorrect merchant category code assigned at onboarding can lock you into a higher rate schedule than your industry warrants. Ask your acquirer to confirm it.
- Audit your pricing model. If you’re on tiered pricing and can’t tell what interchange rate you’re actually paying, ask to move to interchange-plus. The transparency alone often surfaces margin that was hidden in tier mismatching.
- Steer toward debit where the rules allow. Regulated debit transactions cost a fraction of premium credit interchange.
None of this eliminates interchange. But together the steps can meaningfully move the effective rate you pay. On $500,000 in annual card volume, even a 0.20% reduction is $1,000 a year in pure margin.
